CEUS LI-RADS: a pictorial review

AbstractContrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic tool in the imaging work-up of cirrhotic patients at risk for developing hepatocellular carcinoma (HCC). In particular, CEUS Liver Imaging Reporting and Data System (LI-RADS) provides standardized terminology, interpretation, and reporting for the diagnosis of HCC. The aim of this pictorial essay is to illustrate CEUS features of nodules discovered at US in cirrhotic liver according to LI-RADS categorization.

Radu Ioan Badea The emergence of deep-learning methods in different computer vision tasks has proved to offer increased detection, recognition or segmentation accuracy when large annotated image datasets are available. In the case of medical image processing and computer-aided diagnosis within ultrasound images, where the amount of available annotated data is smaller, a natural question arises: are deep-learning methods better than conventional machine-learning methods? How do the conventional machine-learning methods behave in comparison with deep-learning methods on the same dataset? Based on the study of various dee...

The American Institute of Ultrasound in Medicine states that ultrasound providers must be safeguarded from COVID-19 transmission [1]. Additionally, ultrasound examinations should be postponed to prioritize urgent procedures involving percutaneous hepato-biliary drainage and ablation of hepatocellular carcinoma. However, novel means for shielding against patient-generated aerosols remain undeveloped. A negative-pressure room should be prepared to turn off aerosol circulation when performing interventions for patients with COVID-19.

Ultrasound (US)-based screening has been recommended for patients with an increased risk of hepatocellular Carcinoma (HCC). US analysis is, however, limited in patients who are obese or have small tumors. Addition of measurement of serum level of alpha-fetoprotein (AFP) to US analysis can increase detection of HCC. We analyzed data from patients with chronic liver disease, collected over 15 years in an HCC surveillance program, to develop a model to assess risk of HCC.

ConclusionHCCs in NCL have different clinico-radiological characteristics than HCCs in CL. Time of contrast washout correlates with histopathological grade of HCC. Non-cirrhotic NAFLD may require formulation of new screening guidelines for HCC.

Abstract Nonalcoholic fatty liver disease (NAFLD) embraces histopathological entities ranging from the relatively benign simple steatosis to the progressive form nonalcoholic steatohepatitis (NASH), which is associated with fibrosis and an increased risk of progression to cirrhosis and hepatocellur carcinoma. NAFLD is the most common liver disease and is associated with extrahepatic comorbidities including a major cardiovascular disease burden. The non-invasive diagnosis of NAFLD and the identification of subjects at risk of progressive liver disease and cardio-metabolic complications are key in implementing perso...

Authors: Wang Y, Xuan Z, Zheng X, Han R, Zhou L, Liu H, Liu Y Abstract PURPOSE: To evaluate the effect of transcatheter arterial chemoembolization (TACE) under the guidance of contrast-enhanced ultrasound (CEUS) in patients with advanced hepatocellular carcinoma (HCC). METHODS: One hundred and sixty patients with HCC admitted to Cangzhou Central Hospital from April 2015 to April 2017 were enrolled. The clinical data were retrospectively analyzed. Seventy-five patients who underwent TACE according to CEUS results were selected as the observation group. The remaining 85 cases that underwent digital subtraction au...
